Tameness conjecture for generic codimension-one degeneracies

About 1 year old · traced to

Let ∈ˇVect⁡k∗(Ω)\v \in \operatorname{Vect}^{*}_k(\Omega), where Ω\Omega is an open subset of S2S^2 or S2S^2 itself, and suppose that vv contains only a generic degeneracy of codimension 11. Tameness conjecture. The vector field vv is tame, meaning that nearby structurally unstable vector fields orbitally topologically equivalent to vv form a finite-codimensional Banach submanifold. This conjecture would provide the finite-dimensional manifold structure needed to study generic unfoldings and their SET property.
